The blood coagulation system of 66 consecutive patients undergoing liver transplantations was monitored by thrombelastograph and analytic profile. A poor preoperative state, decrease in levels factors, progressive fibrinolysis, whole clot lysis were observed during the preanhepatic anhepatic stages surgery. further general factors platelets, activation abrupt V VIII occurred before with reperfusion homograft. Recovery coagulability began 30-60 min after graft liver, had returned toward...

A venous bypass technique (BP) that does not require the use of systemic anticoagulation is used routinely at our institution in all adult patients during anhepatic phase liver transplantation (LT). Complete cardiopulmonary profiles were obtained a subset 28 consecutive cases. During while on bypass, mean arterial pressure, central and pulmonary wedge pressure maintained prehepatectomy levels. Oxygen consumption fell secondary to decrease temperature removal liver. Consequently, cardiac...

Background: A noninvasive and sensitive imaging tool is needed to assess the fast-evolving baby brain. However, using MRI study non-sedated babies faces roadblocks, including high scan failure rates due subjects motion lack of quantitative measures for assessing potential developmental delays. This feasibility explores whether MR Fingerprinting scans can provide motion-robust brain tissue measurements infants with prenatal opioid exposure, presenting a viable alternative clinical scans....

Light chain amyloidosis (AL amyloidosis) is a haematological disorder in which clonal population of B cells expands and secretes enormous amounts the immunoglobulin light protein. These chains misfold aggregate into amyloid fibrils, leading to organ dysfunction death. We have studied vitro fibril formation kinetics two patient-derived variable domain proteins, designated AL-09 AL-103, response changes solution conditions. Both proteins are members κI O18:O8 germline therefore highly similar...

Total body opacification is the radiological phenomenon in which, after intravenous injection, contrast agent opacifies structures of proportion to their blood supply. Avascular lesions can thus be rendered radiologically visible as lucencies newly contrasting with surrounding opacified structures. Appreciation total effect widely useful diagnostic radiology, especially delineation and characterization neonatal abdominal masses.
